I'll point out that I was testing DuckDB and they have this very nice
feature:
```
D select filename, sum(row_count) as row_count from
read_parquet('/Users/adriangb/Downloads/data2/**/*_stats.parquet',
filename=true) group by filename order by row_count desc limit 10;
Binder Error:
Option filename adds column "filename", but a column with this name is also
in the file. Try setting a different name: filename='<filename column name>'
```
